Explain Energy Level Split for Two Atoms

In summary, the energy levels of a two-atom system are split, allowing for the accommodation of more electrons in each sub-shell. This is demonstrated through the example of two copper atoms combining to form a two-atom system with 58 electrons, which results in the splitting of energy levels and the ability to fit 4 electrons in the 1s sub-shell.

Hi,
can anyone help me explain more detail about energy level split with the system of two atoms?
Please see this video at 06:32:http://www.youtube.com/watch?v=y_GZn4o8gaE
Thank you.

Haha, I have just seen the answer:
Consider 2 atoms of copper. So now we will think of this as a single two-atom system and not as a system with 2 atoms in it. This system now has 58 electrons(not 28 electrons in two atoms). How do we fill these electrons in the sub-shells?The 1s subshell can only accommodate 2 electrons. But we want that it should have 4 e's. So each energy level of the isolated atom splits into two levels for the two-atom system. Thus 4 e's can now be accommodated in the two levels of the 1s sub-shell.
 

FAQ: Explain Energy Level Split for Two Atoms

What is energy level splitting for two atoms?

Energy level splitting refers to the phenomenon in which the energy levels of two atoms are shifted or divided due to their interaction with each other. This can happen when two atoms are in close proximity or when they are bonded together to form a molecule.

How does energy level splitting occur?

Energy level splitting occurs due to the electrostatic interaction between the electrons of the two atoms. When the atoms are close to each other, their electrons repel each other and this leads to a shift in the energy levels of the atoms.

Does energy level splitting affect the properties of the atoms?

Yes, energy level splitting can affect the properties of the atoms. For example, when two atoms are bonded together, the splitting of their energy levels can result in the formation of new orbitals with different energies. This can give rise to new chemical and physical properties in the molecule.

How does energy level splitting relate to the bonding between two atoms?

Energy level splitting is closely related to the bonding between two atoms. When two atoms are bonded together, their energy levels can overlap, leading to the formation of new molecular orbitals. This can result in a stronger bond between the two atoms.

Can energy level splitting be observed experimentally?

Yes, energy level splitting can be observed experimentally through techniques such as spectroscopy. By measuring the energy levels of the atoms or molecules, scientists can determine if there is any splitting occurring and can use this information to understand the properties of the atoms or molecules.
